GENEVA, Nov 28 (Reuters) - A World Health Organization official on Thursday called for stronger surveillance in animals for evidence of infection with H5N1 bird flu in order to curb its spread.
The official also urged stronger efforts to reduce the risk of transmission of the virus to new species of animals and to humans.
"What we really need globally, in the U.S. and abroad, is much stronger surveillance in animals, in wild birds, in poultry, in animals that are known to be susceptible to infection," WHO epidemiologist Maria Van Kerkhove told an online press conference.
